Struct curl::multi::WaitFd

pub struct WaitFd { /* fields hidden */ }

Documentation

File descriptor to wait on for use with the wait method on a multi handle.

Implementations

impl WaitFd

pub fn new() -> WaitFd

Constructs an empty (invalid) WaitFd.

pub fn set_fd(&mut Self, fd: Socket)

Set the file descriptor to wait for.

pub fn poll_on_read(&mut Self, val: bool) -> &mut WaitFd

Indicate that the socket should poll on read events such as new data received.

Corresponds to CURL_WAIT_POLLIN.

pub fn poll_on_priority_read(&mut Self, val: bool) -> &mut WaitFd

Indicate that the socket should poll on high priority read events such as out of band data.

Corresponds to CURL_WAIT_POLLPRI.

pub fn poll_on_write(&mut Self, val: bool) -> &mut WaitFd

Indicate that the socket should poll on write events such as the socket being clear to write without blocking.

Corresponds to CURL_WAIT_POLLOUT.

pub fn received_read(&Self) -> bool

After a call to wait, returns true if poll_on_read was set and a read event occured.

pub fn received_priority_read(&Self) -> bool

After a call to wait, returns true if poll_on_priority_read was set and a priority read event occured.

pub fn received_write(&Self) -> bool

After a call to wait, returns true if poll_on_write was set and a write event occured.
